HGDP K12
HGDP K12 estimates your genetic ancestry using a 12‑component model built on HGDP reference populations. It delivers proportional ancestry signals tied to global groups (West/East Africa, Near East, South/Central/Southeast Asia, East Asia, Europe, the Americas, Oceania), useful for researchers, genealogists, and curious individuals seeking accessible, contextualized insight into population history and admixture.

Über diesen Rechner
The HGDP K12 calculator estimates an individual’s genetic ancestry by comparing their genotype to a curated set of global reference populations derived from the Human Genome Diversity Project (HGDP). Using a 12-component clustering model tailored for modern populations, it quantifies proportional ancestry signals tied to geographically and historically meaningful groups — for example Gambian and Esan (West Africa), Luhya (East Africa), Bedouin (Near East), Irula (South India), Kalash (Central/South Asia), Dai and Japanese (East Asia), Finn (Northern Europe), Karitiana (Native American) and Papuan (Oceania) — plus broad “African (Continent)” representation. The calculator is designed for a worldwide audience: geneticists, population historians, genealogy enthusiasts, students, and curious individuals who want a clearer picture of deep and recent biogeographic ancestry.
Outputs are proportional estimates that highlight major ancestral components in a person’s genome and show how those components map onto historical migrations, population structure, and regional admixture. Users gain insight into continental and subcontinental affinities, detect traces of ancient gene flow (e.g., Eurasian–African exchanges), and compare personal results to known population signatures. The tool contextualizes findings with plain-language explanations so both technical and nontechnical users can interpret results responsibly.
Like all admixture tools, the HGDP K12 model provides probabilistic estimates rather than definitive “labels.” Results depend on the chosen reference set and model assumptions; shared ancestry, recent admixture, genetic drift, and limited reference sampling can blur component boundaries. Despite these limits, this calculator is valuable because it combines a well-documented HGDP reference framework with an intuitive K=12 breakdown, making it useful for exploratory research, teaching, or personal discovery. It helps translate complex population genetics into action

Was ist eine Admixture-Analyse?
Bei einer Admixture-Analyse wird Ihre genetische Ähnlichkeit geschätzt, indem Ihr DNA mit Referenzpopulationen aus verschiedenen Weltregionen verglichen wird. Die Komponenten des Modells stehen für diese Referenzen und hängen von den zugrunde liegenden Daten und Annahmen ab.
Dieser Rechner nutzt 12 sorgfältig ausgewählte modern Populationen als Referenzen und ermöglicht eine detaillierte Darstellung Ihrer genetischen Ähnlichkeit.
So funktioniert es
- Ihr DNA wird mit 12 Referenzpopulationen verglichen
- Modern-Populationen dienen als genetische Referenzen
- Die Ergebnisse zeigen Ihre genetische Ähnlichkeit zu diesen Populationen
- Ein vielfältiges Referenzpanel verbessert die Schätzungen
Ihre Ergebnisse verstehen
Ihre Ergebnisse zeigen Prozentsätze der genetischen Ähnlichkeit zu diesen Referenzpopulationen. Beachten Sie diese Punkte:
- Die Ergebnisse spiegeln genetische Ähnlichkeit wider, nicht nachgewiesene direkte Abstammung
- Modern-Populationen werden als Referenzen verwendet
- Die Prozentsätze geben relative Beiträge im Modell an
- Die Ergebnisse sind Schätzungen auf Basis der verfügbaren Referenzdaten
